DonManfred · Jan 31, 2015

SignPad
Version: 0.20

Android Signature Pad is an Android library for drawing smooth signatures. It uses variable width Bézier curve interpolation based on Smoother Signatures.

For those who want to play with the library or mayybe to extend
i have included the java source of this library so you can change it by yourself and then recompile the lib with SLC. Have fun

This wrapper is based on this

SignPad

- AddToParent (Parent As ViewGroup, left As Int, top As Int, width As Int, height As Int)
- Capture
- DesignerCreateView (base As PanelWrapper, lw As LabelWrapper, props As Map)
- Initialize (EventName As String)
- clear
- getAlbumStorageDir (albumName As String) As File
- saveBitmapToJPG (bitmap As Bitmap, photo As File)
Properties:
- Left As Int

There ´ll be no more versions. As the library is from 2015 i know i do not have the source anymore (HDD crash in 2016).
Do not expect any new here. Use the library in #1. Example is in #1 too.

If it´s fit your needs; great. If not; search for alternatives.

Yes I believe that's the one that I used.. with a signature area not enough.. (the height)

sure post it

netsistemas · Jun 27, 2022

This is the original source code for develpment in eclipse/java, and other with a little change for my proyect (touchmadmio) (point over de 'i' are not allowd in original).

inside tochpadmio, have the folfer 'libreriasparab4a': jar and xml

i'm not sure this code are that you need or other more old.

Please enable the onClear event.

netsistemas · Nov 25, 2024

I encourage you to do it. I can't right now, maybe next week. It is not complicated and you will open up new possibilities.

netsistemas · Nov 25, 2024

(in spain we say: 'el rascar es todo empezar' - scratching is all beginning)

doit:
- install eclipse
- do a simple change:
* in signPad.java added this code:

ba.raiseEvent(this, eventName + "_onclear");

B4X:

    @Override
      public void onClear() {
          BA.Log("onClear() evento rav");

          ba.raiseEvent(this, eventName + "_onclear");
          //mSaveButton.setEnabled(false);
          //mClearButton.setEnabled(false);
      }
    };

- install https://www.b4x.com/android/forum/t...-libraries-without-eclipse.29918/#post-173756
and compile

problems:
* b4DocLet are not in my computer (view previous thead)
* case sensitive : ba.raiseEvent(this, eventName + "_onClear"); (C in Clear must be minus!!)

And now, incluye in your B4A proyect the detect event:

B4X:

Sub SignaturePad_onSigned(sign As Object)
    If ValidarDniYNombre = False Then
   
        SignaturePad.clear
        SignaturePad.Tag = ""
        MsgboxAsync("Complete Nombre y apellidos,  y  DNI con 9 caracteres. No indique guiones","Faltan datos")
    Else
        SignaturePad.Tag = "Firmado"
    End If
   
End Sub


'this event are raised a lot of times.
Sub SignaturePad_onClear()
'    MsgboxAsync ("Borrado","Borrado")
End Sub

importan:
may be is better use:

SignPad V0.20 - Signature Capture - incl Java source

SignPad Version: 0.20 Android Signature Pad is an Android library for drawing smooth signatures. It uses variable width Bézier curve interpolation based on Smoother Signatures. For those who want to play with the library or mayybe to extend i have included the java source of this library so...

www.b4x.com

now i have a problem with this library in my proyect:
error pasing librarie
com.github.gcacace.signaturepad.views
signaturepad.strokewidth alrady existe
and the version is 0.0 with the previous are 0.22
i think the problem is the commple method ( in previus version 5 year ago!!! i compile with javadoc ...)
i go to use the previous version in my proyect.

my be the correct implements are in official touchpad of DonManfred.

(at the risk of being annoying, but for leaving everything documented

You have to include com.github in the compiler that I mentioned, as I have seen in another thread.
This is:
-b4aignore: org,com.android,com.example,com.hoho,com.github

But anyway the XML has some different entries that makes my project fail to compile.

Attach images.
